Disclosed is a device for dispensing fluid material. In particular, the disclosure relates to 11 dispensing spreadable foodstuffs evenly from a container without the need of a knife or other 12 utensils not part of the food packaging.

14 Spreadable foodstuffs, as packaged currently, require opening at least one package, then using an external device such as a knife or spreader to remove the contents from the 16 package, and ultimately to spread onto the food item. Applying spreadable foodstuffs such as 17 ketchup, mustard, cream cheese, peanut butter, jelly, vegemite, nutella, and the like from 18 conventional packaging requires a great deal of patience, coordination, and is almost assuredly 19 a two-handed affair. Squeezable bottles reduce the need for a device to remove the contents from the packaging, but still require an external utensil to spread the contents on the surface.
21 Further, as the contents are consumed the void space inside the squeezable container grows, 22 causing well-known difficulties with such containers such as splatter, unappetizing noise, and 23 poorly mixed contents. Another problem caused by the void space is the adverse affect the air 24 that occupies the space causes to the contents within.

Traditional packaging is also challenging for children, elderly persons, persons with 26 disabilities, and physically challenged individuals to use. The utensils used to remove and 27 spread the contents of the packaging must be washed after every minor use, which is a 28 particular inconvenience during such activities as traveling, picnics, and other occasions where 29 typical kitchen amenities are not present.

Another shortcoming of conventional packaging is the inability to accurately measure the 21947540.1 1 Agent Ref: 75819/00002 1 dispensed quantity. Each surface that comes into contact with spreadable foodstuffs retains a 2 small amount on its surface, so precise measurements are difficult to obtain. Measuring cups 3 provide some relief, but very viscous foodstuffs such as peanut butter and cream cheese are 4 difficult to measure this way since an accurate measurement may only be achieved by packing the product, which is messy and causes further measurement inaccuracies.
Moreover, once the 6 precise amount is within the measuring cup, the same problems exist in removing the foodstuffs 7 from the measuring cup. A solution to accurate measurement and use of spreadable foodstuffs 8 is particularly pertinent for portion control, dieting, and restaurant settings where consistency is 9 important.

The difficulties and inconveniences described above are also found with a variety of non-11 food semi-solid or gelatinous substances. These substances include but are not limited to 12 toothpaste, shoe polish, paints, cosmetics, thick oils, topical medications, emollients, and the 13 like.

The following presents a simplified summary of the invention in order to provide a basic 16 understanding of some aspects of the invention. This summary is not an extensive overview of 17 the invention. It is intended to neither identify key or critical elements of the invention nor 18 delineate the scope of the invention. Rather, the sole purpose of this summary is to present 19 some concepts of the invention in a simplified form as a prelude to the more detailed description that is presented hereinafter.

21 The subject invention provides for fluid material, including but not limited to spreadable 22 foodstuffs, to be packaged in a container that can include means for spreading the fluid 23 material. The innovative packaging can perform the role of dispensing and spreading, obviating 24 the need for additional utensils to remove the material from their packaging and to spread them onto a surface. Pressure can be applied to a chamber that contains the material, causing 26 expulsion from a strategically placed aperture or apertures located on or near a substantially 27 broad, flat surface that facilitates spreading the material on a surface.
The chamber can be 28 deformed or altered to create the pressure, and the change can be maintained between 29 dispensing instances so as to reduce void space in the chamber and thus maintain freshness.
In an aspect of the subject innovation, pressure can be applied in the chamber by means 31 of a powered device such as a motor (electric or otherwise), pneumatic equipment, hydraulic 32 equipment. The powered device can include an on/off switch that can be operated by a user to 21947540.1 2 Agent Ref: 75819/00002 1 cause dispensing of the contents of the chamber during desired intervals.
The switch can be a 2 typical on/off switch, where the current status will persist unless switched by the user, or a 3 biased switch where pressure, power, or other influence from the user is required to maintain 4 the unbiased position. Manual pressure or power can supplement or supplant the powered pressure, and can be assisted by a rotating finger screw, a lever, a pump, a squeezable 6 chamber, and the like.

7 In another aspect, the subject innovation provides an at least two-part system, where 8 one part contains the foodstuffs, and the other part contains the mechanism that applies the 9 pressure to the chamber. A third part, containing the apertures and the spreading surface, can form part of either of the first two parts, or can stand alone. The separate parts can fasten 11 together using any known means. Any one or combination of these parts can be disposable or 12 reusable. Alternatively, the innovative apparatus can be a unitary device that can be reusable 13 and accept refill contents, or disposable and provide one-time use.

14 An embodiment of the subject innovation comprises a toothbrushing apparatus. The fluid material in this aspect can be toothpaste or other mouth cleaning agent, and the dispensing 16 portion is a toothbrush. In response to applied pressure, the toothpaste can be dispensed into a 17 toothbrush attachment and onto bristles which can surround the aperture (or apertures) 18 providing uniform dispensing of the toothpaste onto the brush. A user can obtain a retail tube of 19 toothpaste for use with the tooth-cleaning apparatus. Only one hand is required for use, rendering the apparatus much more accessible for individuals of varying levels of coordination.
21 The toothbrush portion can be an attachment that can be replaced as often as desired, fastened 22 to an end of the apparatus. In another related aspect, the apparatus can be sold as a unitary 23 article of manufacture. Alternatively, the user can simply purchase the apparatus containing a 24 single use reservoir of toothpaste, use the brush and toothpaste until finished, and then discard the apparatus.

26 A related aspect of the subject innovation provides for a fluid material dispenser that 27 implements a multiplicity of shapes, spreading surfaces, aperture arrangements, and aperture 28 shapes. Interchangeable spreading surfaces can be chosen for different applications. The 29 viscosity of the dispensed material, the surface onto which the material is to be dispensed, and any other pertinent variable can affect the choice of spreader configuration.
For a fluid of low 31 viscosity, the apertures can be smaller and more numerous, for example, while a highly viscous 32 fluid such as peanut butter can have fewer, larger holes. In addition, the shape of the 33 dispensed fluid can be altered by the choice of a spreader configuration.
The shape of 21947540.1 3 Agent Ref: 75819/00002 1 individual apertures can vary, and include shapes such as stars, hearts, and the like; also, the 2 arrangement of a plurality of apertures relative to one another and the spreading surface can be 3 modified to accommodate a desired output. The spreader shape and/or Irregular stripe 4 patterns, for example, can be spread by an irregular pattern of apertures on the spreader. In another related aspect, novelty or affinity spreaders can be used, taking the form of an object 6 such as a baseball bat, a cartoon character, a wand, and the like. Also, the apertures 7 themselves, and/or their relative position, can represent, or dispense, an affinity figure.

8 To the accomplishment of the foregoing and related ends, the invention comprises the 9 features hereinafter fully described and particularly pointed out in the claims. The following description and the annexed drawings set forth in detail certain illustrative aspects and 11 implementations of the invention. These are indicative, however, of but a few of the various 12 ways in which the principles of the invention may be employed. Other objects, advantages and 13 novel features of the invention will become apparent from the following detailed description of 14 the invention when considered in conjunction with the drawings.

4 The various aspects of the subject innovation are now described with reference to the annexed drawings, wherein like numerals refer to like or corresponding elements throughout. It 6 should be understood, however, that the drawings and detailed description relating thereto are 7 not intended to limit the claimed subject matter to the particular form disclosed. Rather, the 8 intention is to cover all modifications, equivalents, and alternatives falling within the spirit and 9 scope of the claimed subject matter.

The word "exemplary" is used herein to mean serving as an example, instance or 11 illustration. Any aspect or design described herein as "exemplary" is not necessarily to be 12 construed as preferred or advantageous over other aspects or designs.
Furthermore, examples 13 are provided solely for purposes of clarity and understanding and are not meant to limit the 14 subject innovation or relevant portion thereof in any manner. It is to be appreciated that a myriad of additional or alternate examples could have been presented, but have been omitted 16 for purposes of brevity. Furthermore, all or portions of the subject innovation may be 17 implemented as a method, apparatus or article of manufacture using standard engineering 18 techniques.

19 Fig. 1 depicts an apparatus that dispenses and facilitates spreading of a fluid material onto a surface. It is to be appreciated that the fluid material and the receiving surface can 21 comprise virtually any fluid material and surface combination, and the principles of the invention 22 can be practiced in any appropriate field where it is advantageous to dispense or spread a fluid 23 material on a surface. The term "fluid" herein connotes the technical definition of fluid: any 24 material that deforms under any shear force. Fluid material may contain objects that are not fluid (e.g., chunky peanut butter, baby food, etc.), or be fluid at certain temperatures or 26 conditions and not others, and still fall within the definition of fluid.
The examples used 27 throughout this application are but a small illustration of possible applications of the subject 28 disclosure, and one having ordinary skill in the art will appreciate that the subject innovation is 29 not limited to the examples discussed herein.

Apparatus 100 is an apparatus that dispenses fluid material and facilitates spreading of 31 the material on a surface. In an aspect, the apparatus 100 is a hand-held device that dispenses 32 edible fluid material onto another edible surface (e.g., butter, spread on bread). Apparatus 100 21947540.1 5 Agent Ref: 75819/00002 1 can comprise a unitary, one-piece construction, or can be composed of a plurality of 2 connectable parts that can be fastened together. A chamber 110 can contain the fluid material 3 which is to be dispensed from the apparatus 100 and spread onto a surface.
For example, 4 chamber 110 can contain butter or another substance that is to be spread onto a slice of bread for consumption. Chamber 110 can be constructed of a flexible material, and can be deformed 6 under pressure to cause the material within to exit the chamber and eventually reach the target 7 surface. Chamber 110 can include graduation markings and a transparent portion to permit 8 inspection of the contents of the chamber and the quantity remaining within the chamber.
9 Alternatively, the chamber 110 can comprise a more rigid material with a plunger at the base which can be driven toward a distal end of the apparatus 100 to cause expulsion of the 11 contained material. In the case of a multi-part composition of apparatus 100, chamber 110 can 12 be constructed to contain a set amount of material, and when the material is exhausted a new 13 chamber 110 containing a fresh supply of material can be introduced and used. In the case of a 14 unitary construction, the entire apparatus can be discarded once the material in the chamber 110 is spent. In this case, it can be desirable to construct the apparatus 100 of a more 16 inexpensive construction, as will be more fully described below.

17 Apparatus 100 also can include a body 120 which comprises the main housing for 18 internal components. In an aspect, body 120 comprises a sleeve-like construction which can 19 receive a chamber 110. Body 120 can also serve as the primary means for holding the apparatus 100, and as such can be ergonomically shaped, and be constructed of a material 21 pleasing to the touch, and can take an attractive shape and size. A base portion 130 can 22 include a substantially flat bottom surface to facilitate placing the apparatus on a flat surface in a 23 stable manner. Base portion 130 can also house any electrical components and/or a motor or 24 other power source adapted to create pressure on the contents of the chamber 110 to expel the material from the chamber. A grip portion 140 can accommodate a user's thumb or other part of 26 the hand to facilitate confident grasping of the apparatus. Further, grip portion 140 can include 27 a depressible button that can operate some component of the apparatus 100, such as the 28 mechanism for creating pressure on the contents of the chamber 110. Such a button can be 29 located in any convenient location on the apparatus 100, and can comprise virtually any appropriate mechanism (biased or otherwise) such as a lever, a switch, a button, a knob, a 31 handle, and the like. For purposes of brevity, this aspect will be described herein as a biased, 32 depressible button.

33 In order to supplement (or, in an aspect, supplant) the operation of the power source, a 21947540.1 6 Agent Ref: 75819/00002 1 manually rotatable wheel 150 can be employed to create pressure on the contents of the 2 chamber. This wheel 150 can be recessed below the surface of the body 120 to ensure that 3 only deliberate action by the user will cause rotation. An errant hand motion is unlikely to turn 4 the wheel 150 and perhaps disrupt smooth operation of the apparatus, while intentional access to the wheel 150 is not hampered. It is to be appreciated that a wheel configuration as shown is 6 only one of many possible means for creating manual pressure, and the subject innovation is 7 not limited to the examples shown and described in any way.

8 Pressure in the chamber 110 can cause the material inside the chamber 110 to exit the 9 apparatus 100 through an aperture 160 (or apertures) in the spreading portion 170. Once the material has exited the spreading portion 170 through the apertures 160, the spreading portion 11 can facilitate spreading of the material onto a surface. In the aspect shown, spreading portion 12 170 comprises a broad, relatively flat surface that can adequately spread the material onto the 13 surface. However, the spreading portion 170 can comprise virtually any shape and aperture 14 configuration 160 to accommodate the material to be dispensed, and the surface onto which the material will be spread. In the multi-part aspect mentioned above, the spreading portion 170 16 can be a separate part, which can be fastened to the remainder of the apparatus 100, and as 17 such can be chosen for different materials, surfaces, and applications. In the case of a unitary 18 construction, the shape and aperture arrangement of the spreading portion 170 can be chosen 19 appropriately as well, depending on several variables including viscosity and make-up of the material, the type of surface that receives the material, and so forth.

21 Fig. 2 depicts an internal view of an apparatus 200 that can dispense a fluid material and 22 facilitate spreading of the material on a surface. Body 202 can serve as the handling portion of 23 the apparatus 200, and thus can be shaped and sized in an ergonomic, attractive manner.
24 Chamber 204 can contain the fluid material to be dispensed; chamber 204 can itself be housed within body 202. In the example shown, body 202 and chamber 204 are coaxially related, and 26 are substantially cylindrical in shape. However, it is to be appreciated that a multitude of shapes 27 can be employed to house a chamber within a body without departing from the scope or spirit of 28 the subject innovation. To dispense the fluid material, pressure can be applied to the material 29 within the chamber 204. This can be accomplished in a variety of ways, one of which is depicted here as a central threaded member 206, a plunger 208, and a mechanism of driving 31 the plunger 208 toward the distal end 210 of the apparatus 200. In this example, the threaded 32 member 206 is rotated by a motor 212. The motor can be powered electrically, or by any other 33 means of creating a torque on the threaded member 208, rotation of which causes plunger 208 21947540.1 7 Agent Ref: 75819/00002 1 to move toward the distal end 210 of the apparatus 200, and expel the material from the 2 chamber 204. The motor 212 can include a microprocessor to control the power output by 3 monitoring variables such as rotation speed, pressure output and the like. A
button 214 can be 4 located on the body 202 or other appropriate location which can be in electrical contact with motor 212 by way of a wire 216. Depressing the button 214 can cause an electrical signal to 6 travel to motor 212, engaging the motor 212 to rotate the threaded member 206.

7 In an aspect, button 214 (in conjunction with other, internal and/or external components) 8 can facilitate metered dispensing of material. A user can determine an amount of material to be 9 dispensed, and enter this information into the apparatus and when the button 214 is depressed, the determined amount is dispensed. The user can input the desired amount by means of a dial 11 or a digital LCD screen (neither shown) in a manner well known in the art.
Pressure can be 12 applied continuously or increasingly until the proper amount has been dictated. The apparatus 13 200 can measure the displacement or deformation of the chamber 204 in order to calculate 14 when a sufficient amount of material has been dispensed. In the example shown, a relatively precise measurement of material can be interpreted directly from the rotations of the threaded 16 member 206. The pitch of the threads, and the volume of the chamber are all the information 17 needed to calculate an accurate quantity as a function of rotations.
Depending on the 18 configuration of the chamber and the source of the pressure, there are metrics available to 19 determine the quantity of material dispensed.

Depending on certain variables such as the viscosity of the material in the chamber 204, 21 the shape and arrangement of the exit apertures, the surface to receive the expelled material, 22 and the like, the motor 212 can supply differing levels of pressure to the chamber 204. In the 23 case of a highly viscous material, more power can be drawn from the motor to compensate for 24 the resistance caused by the high viscosity. In addition, a modified gear ratio can be chosen to accommodate a more viscous material; slowing down the rotation, but increasing the torque 26 applied to the material can be a beneficial configuration. In an aspect, a manual power input 27 can be included to supplement or supplant the power from the motor. In the exemplary 28 embodiment shown, a manually rotatable wheel 218, located coaxially with threaded member 29 206 and motor 212, can be accessed through a recess 220 in the body 202.
Turning the wheel can exert the same force upon the chamber 204 as caused by the motor 212, and can be used 31 to assist the motor if the material does not flow uniformly or as desired.
The recess 220 can 32 serve to ensure that only deliberate efforts to rotate the wheel 218 will cause rotation thereof, 33 while not significantly obstructing access to the wheel 218. In an aspect, the motor can sense 21947540.1 8 Agent Ref: 75819/00002 1 when the wheel 218 is being rotated by a user, and cease operation despite depression of the 2 button 214. In this manner, the user's torque will not interfere with the motor 212, and vice 3 versa. In another aspect, the manual input can supplement the motor's 212 operation, or the 4 motor 212 can be omitted completely, leaving the manual input of power the sole source of pressure used to dispense material.

6 The above discussion of the motor 212 and wheel 218 are, of course, merely one 7 example of a configuration of the apparatus 200 according to the subject disclosure. As will be 8 appreciated by one having ordinary skill in the art, there are myriad equivalent sources of power 9 that can be used to create the necessary pressure to dispense the material from chamber 204.
The pressure application mechanism can include a pneumatic pressure source brought into 11 communication with the chamber 204, and an increase in the pneumatic pressure can cause the 12 material in the chamber 204 to be dispensed. The pneumatic pressure can be created by a 13 motor located at the base of apparatus 200 (much like motor 212) or can be supplied through a 14 hose or tube connected with an external source of pneumatic pressure, as is well known in the art. Hydraulic pressure can be employed in substantially the same manner as pneumatic 16 pressure. Moreover, pressure can be created by squeezing the chamber 204 transversely, 17 deflecting the side walls inward. Any of these approaches to creating pressure in the chamber 18 can be powered by an internal power source (e.g., battery, fuel cell) or by manual exertion by 19 the user.

In another aspect of the subject disclosure, the material inside the chamber 204 is kept 21 from excessive contact with external elements such as air, by reducing the internal dimensions 22 of the chamber 204 eliminates or substantially reduces the amount of void space within the 23 chamber. In contrast, a conventional packaging arrangement creates void space equal in 24 volume to the product dispensed from the packaging (e.g., mustard bottles, cream cheese tubs, jelly bottles), severely damaging product freshness. To mitigate this situation, as plunger 208 26 moves toward the distal end 210 of apparatus 200, void space 222 behind plunger 208 is kept 27 out of contact with the material.

28 Fig. 3 depicts interaction of two components that make up an apparatus 300 that 29 dispenses fluid material and facilitates spreading the material. As described above, the apparatus 300 can be formed of a unitary construction, designed for a single use. The 31 embodiment shown in Fig. 3, however, shows a multi-component configuration, where sub-32 components can fasten together to form the apparatus 300. Cartridge 302 can be shaped to fit 33 within body 304, and be secured by a snap-mechanism, a friction fit, a threaded engagement, a 21947540.1 9 Agent Ref: 75819/00002 1 vacuum seal, or any other equivalent fastening mechanism as is known in the art. Cartridge 2 302 can serve as the chamber containing the fluid material, as described above with respect to 3 Figs. 1 and 2. In addition, cartridge 302 can contain a liner (not shown) made of more flexible 4 material that houses the fluid material and is deformed under pressure to expel its contents as desired. In an aspect, body 304 can be constructed for relative long-term use, and can receive 6 a plurality of cartridges 302, which can be disposable. Threaded member 306, shown here as 7 part of the cartridge 302, can also form part of the body 304 and can include a keyed portion 8 308 that interacts with a corresponding surface 310 on the body 304. Their interaction can 9 serve as the mechanism of delivering power from the motor 312 (or other power source) to the contents of the cartridge 302. A button 314 can be adapted to release the cartridge 302 from 11 the body 304 for disposal.

12 Fig. 4 depicts a spreader portion 400 in greater detail. The spreader portion 402 can be 13 fastened to the cartridge shown in Fig. 3, or to the distal end of the apparatus shown in Fig. 1 14 and 2. In the case of a unitary construction, the spreader portion 402 can form part of the assembly. In any case, this portion can operate to dispense the fluid material and facilitate 16 spreading of the material onto a surface. The bottom edge 404 of the spreader portion 402 and 17 the recess therein can be brought into communication with the chamber described above.
18 Pressure applied to the material in the chamber can cause the material to enter the spreader 19 portion 402 in the recessed area 406 and upward until it reaches the apertures 408, where the material exits the apparatus. The design shown here is for exemplary purposes only, and in no 21 way is the subject disclosure limited to the shape, size, or arrangement of the spreader portion 22 402 or the apertures 408. In this example, aperture 410, located at a greater distance from the 23 source of the pressure below, is larger than apertures 412 and 414 to dispense a uniform 24 amount of material. The dimensions and arrangements of the apertures 408 and the spreader portion 402 can be chosen according to principles of fluid dynamics, which are generally well 26 known in the art. In addition, special apertures (not shown) can be implemented to allow for 27 chunky material to be distributed. Materials such as chunky peanut butter with sizable of non-28 fluid peanut pieces, or raspberry preserves with non-fluid seeds, can dictate the use of special 29 apertures that accommodate the non-fluid chunks in the material and distribute as desired.

Spreading surface 416 can be constructed as a broad, flat surface that facilitates 31 spreading the fluid material. In the embodiment shown, spreading surface 416 resembles a 32 knife - the most common utensil used for spreading - however, any shape or surface can be 33 employed according to the need of a particular application. For instance, a concave, spoon-like 21947540.1 10 Agent Ref: 75819/00002 1 shape may be a preferred shape in a given circumstance, or a rough, uneven surface, or a 2 rounded convex surface. It is to be appreciated that the subject innovation is not limited to the 3 examples shown or described, as will be appreciated by one having ordinary skill in the art. A
4 cap 418 can cover the spreading portion 402 and the apertures 408 to maintain freshness. The base portion 420 of the cap 418 can include a friction fit, a snap fit, or a threaded engagement 6 to secure the cap 418 to the spreading portion 402. For ease of removal, a finger ridge 422 can 7 be included.

8 Fig. 5 illustrates another embodiment, a fluid material dispensing apparatus 9 comprising a toothbrush and toothpaste dispenser. The main body portion 502 of the apparatus 500 can contain toothpaste or other tooth cleaning solution in a reservoir 504. Pressure can be 11 applied to the toothpaste to cause expulsion from the reservoir 504 and onto a brush 506, which 12 can then be used to brush teeth. At a distal end of the apparatus 508, a brush attachment 506 13 can be fastened containing bristles 510 and an aperture 512 (or apertures) located near the 14 base of the bristles 510. Pressure in the reservoir 504 expels toothpaste from the aperture(s) 512, permitting simple tooth cleaning.

16 Apparatus 500 can be constructed as a unitary article, which can be sold as a unit and 17 used until reservoir 504 is empty or until the brush 506 needs replacing, whichever happens 18 first, at the discretion of the user. According to this aspect, the entire unit can be discarded and 19 replaced. In another related aspect, the brush 506 and the reservoir 504 can be replaced, and the body 502 can be reused with new a reservoir 504 and brush 506. In the case of the 21 reusable body 502, a replaceable reservoir 504 can comprise an ordinary retail tube of 22 toothpaste of any size, and can be inserted into the body 502. At a distal end 508, the opening 23 514 of the tube can be connected to a corresponding opening in the body 502 that permits the 24 toothpaste to flow from the tube 504 into the brush 506, and eventually onto bristles 510 for use.
To accommodate several sizes of toothpaste tube openings, an adjustable adapter, or a set of 26 a number of standard sized adapters, can be provided. At a proximal end 516 of the apparatus 27 500, a variety of different pressure-applying mechanisms can be employed to expel toothpaste 28 from the reservoir 504, and an equally varied number of power sources can be utilized.

29 In one aspect, a roller 518, located initially near the proximal end 516, can be rolled toward the distal end 508, forcing the toothpaste from the reservoir 504. This mechanism can 31 be powered by an electric motor (or other automated means of power delivery) or by manual 32 input by means of a rotor, a dial, a lever, or crank, or the equivalent.
Automated means of power 33 delivery (e.g., a motor) can also be combined with manual power input (e.g., crank, lever, dial).
21947540.1 11 Agent Ref: 75819/00002 1 An advantage of this aspect is afforded because the roller simulates a common method of 2 extracting toothpaste from conventional toothpaste tubes, but accomplishes the end in a more 3 simple, elegant manner. In another aspect, in place of a roller, a proximal end 516 of the 4 reservoir 504 can be grasped by opposing finger-like members which can be rotated in substantially the same manner as the roller 518, causing the tube to roll toward the distal end 6 508, forcing toothpaste from the reservoir 504. The reservoir 504 can be held in tension 7 between its opening 514 and the proximal end 516 to extract the maximum amount of 8 toothpaste from the reservoir, without stranding residual toothpaste in the resultant rolled portion 9 of the empty reservoir.

Fig. 6 shows another aspect of the subject innovation, featuring a plunger, which can 11 operate in a similar manner as described elsewhere herein. An encasing 604 can receive a 12 reservoir 606 containing toothpaste or other tooth cleaning solution.
Reservoir 606 can be an 13 ordinary tube of toothpaste or a tube dimensioned for specific use with encasing 604. An 14 opening 608 can communicate with a brush attachment as shown and described with respect to Fig. 5. As with other components disclosed herein, the component parts (or any sub-set 16 thereof) of the apparatus 600 shown and described can be designed for continued use, or for a 17 short lifespan. For example, encasing 604 can be constructed of a more durable material, 18 configured to accept several reservoirs 606 and to dispense the material held in the reservoirs 19 606; or, reservoir 606 can be filled with fluid material repeatedly as needed and re-used. The design of the apparatus, and the various embodiments described herein, offer several distinct 21 advantages over conventional toothpaste dispensing configurations. For example, traditional 22 toothpaste dispensing means, which are packaged separately from the toothbrush, require a 23 complex and cumbersome operation to place toothpaste onto the bristles of a brush before use.
24 Unmixed toothpaste, as dispensed from traditional packaging, does not reach its cleansing potential unless and until it is mixed with water in the mouth, and vigorously brushed against 26 and between the teeth. However, toothpaste placed precariously upon the end of upright 27 bristles is prone to leave the bristles, so the brusher must hunt the unmixed mass of toothpaste 28 in the mouth, mix it with water, and only then can actual brushing commence.

29 In addition to use as a toothbrush, apparatus 600 can be used with any other type of brush for a variety of different applications. A shoe-shining brush can be used, with the fluid 31 material in the reservoir being shoe-polish. A dish-washing brush with soap, a toilet-brush with 32 toilet cleaner, a floor-cleaning brush with floor cleaner, a polishing brush with or without a fluid 33 material used to polish, and a hair brush with hair spray, pomade, or other hair-care product, are 21947540.1 12 Agent Ref: 75819/00002 1 all examples of appropriate uses for the disclosed apparatus. It is to be appreciated that the 2 foregoing examples are merely for illustration, and that the subject disclosure is not limited to 3 the examples given here.

4 Fig. 7 shows a plurality of spreading/dispensing portion and aperture shape configurations that can be implemented in accordance with the subject disclosure. For 6 purposes of clear description, each is shown as an attachment to an apparatus as described 7 above. It is to be appreciated that each of these attachment designs (and their equivalents) can 8 be implemented in a unitary, one-use application of the apparatus as has been disclosed herein.
9 Attachment 702 includes a knife edge 704 which can be used to cut as well as to spread. The apertures 706 are placed adjacent to the knife edge 704 to deliver the fluid material directly to 11 the spreading surface 708 of the knife edge 704. Attachment 710 shows a slightly larger 12 spreading surface 712 and an elongated aperture 714. As with attachment 702, aperture 714 is 13 located near the spreading edge 712. Attachment 720 features two edges 722 and 724, with 14 apertures 726 located adjacent only edge 722. Fluid material can be dispensed from the apertures 726 and spread by edge 722, leaving edge 724 free of fluid material for clean cutting, 16 for example. Attachment 730 features a broad, serrated edge 732 with dispensing apertures 17 734 near by, while attachment 740 shows a serrated edge 742 with little or no spreading 18 surface. It is to be appreciated that the arrangements and designs of the attachments depicted 19 in Fig. 5 are for illustrative purposes only, and the subject disclosure is not limited to the configurations shown here. One having ordinary skill in the art will appreciate that the features 21 of the attachments can be implemented in any combination, and that designs not specifically 22 shown here fall within the scope of the subject innovation.

23 Figs. 8 and 9 depict a plurality of different configurations and arrangements, all of which 24 are contemplated for use with the apparatus as described herein. As with the attachments of Fig. 7, it is to be appreciated that the arrangements and designs of the attachments here 26 depicted are for illustrative purposes only, and the subject disclosure is not limited in any way to 27 the configurations shown here. One having ordinary skill in the art will appreciate that the 28 features of the attachments can be implemented in any combination, and that designs not 29 specifically shown here fall within the scope of the subject innovation.

What has been described above includes examples of aspects of the claimed subject 31 matter. It is, of course, not possible to describe every conceivable combination of components 32 or methodologies for purposes of describing the claimed subject matter, but one of ordinary skill 33 in the art may recognize that many further combinations and permutations of the disclosed 21947540.1 13 Agent Ref: 75819/00002 1 subject matter are possible. Accordingly, the disclosed subject matter is intended to embrace 2 all such alterations, modifications and variations that fall within the spirit and scope of the 3 appended claims. Furthermore, to the extent that the terms "includes," "has"
or "having" or 4 variations thereof are used in either the detailed description or the claims, such terms are intended to be inclusive in a manner similar to the term "comprising" as "comprising" is 6 interpreted when employed as a transitional word in a claim.
